I am holding \'L1-A\' visa now. I submitted my I-485 on June 2001, and just got the approval notice this week. I know that I need to go to INS office to do the fingerprints and passport stamping to complete the whole process. My question is that because I\'m on business trip outside U.S. until end of this year, and if I do it at that time, any impact ? Is there any time frame to complete the whole process ? By the way, my Visa will be expired on June of 2003.
